摘　　要：运用Preissmann四点隐式格式对一维圣维南方程组进行求解,建立长江三峡水库一维水动力数学模型,并从水位、流量、流速等方面分析库区水流运动规律。采用VB编程实现了图形界面与Fortran计算程序的数据交互,通过混合编程技术生成动态链接库将两者连接起来,成功实现了一维水动力数值模拟和动态显示的一体化,研究成果的应用对于三峡水库的运行调度具有参考与支持作用。The Preissmann＇ s four point implicit difference scheme is used to solve Saint-Venant equations, and then the 1-D hy- drodynamic mathematic model of Three Gorges Reservoir is developed, furthermore, the flow movement law of the reservoir area is analyzed in the aspects such as the water level, discharge, velocity, etc. Moreover, the data exchange between the graphical interface and Fortran computer programs is realized based on VB programming and the connection between both of them is taken on by dynamic data linkbase generated through mixed programming; from which the integration of 1 D hydrodynamic numerical simulation and dynamic display is successfully implemented. The applications of the study result can play a reference and support role in the operation management of Three Gorges Reservoir.
